This mod allows some simple control over train schedules using special signals.

The 'Refuel' signal: If this signal is found in the station name, the train will skip over the station if it has enough fuel.
The 'Depot' signal: If this signal is found in the station name, the train will skip over the station if its next destination is open and has enough space.

NOTE: The depot signal only works if the train stops are using train limits.
NOTE: the depot signal does not work with Circuit network disabled stations, as the base game does not dispatch the train.

You can combine both signals, to make a 'Refuel Depot'. In this case, a train will only go to the station if it needs to refuel or if its next destination is closed.

There is no clever logic, there is no automatic schedule insertion or changing. You decide which refuel and which depot stations a train should go to.

You can have multiple stations using the signals, the trains will only ever go to the stations you set in the schedule. So for instance you can have 1-2 trains go to 'Refuel 1-2' station, and 1-4-1 trains go to 'Refuel 1-4-1'.

If you see the 'Skip' signal in the train schedule, it means that the train is going to skip over that station Do not be alarmed by it, and do not use the skip signal in a station name.
